The object of this study is to report a clinical effect regarding the conservative treatment of the patients who were diagnosed as the herniated intervertebral lumbar disc(HIVD). The patients were treated by the oriental medical conservative treatment including acupunture, Bee venom therapy and Chu-na therapy. We estimated by visual analogue scale and pain rating score subjectively. And we examined the patients with SLR test and valsalva test. Oriental medical conservative treatment improved HIVD subjuctively and objectively.

A retrospective in vivo study of endodontically treated mandiblar molars was conducted. The radilographs and clinical records of mandibular molars that had been treated endodontically in the Dental hospital of Yonsei University from 1986 to July 1997 were reviewed and categorized. A total of 1751 cases were studied and following results were obtained. 1. The number of root canals in mandibular first permanent molar in a Korean population revealed three in 53.2 %, four in 23.0 %, two in 18.4 %, C-shaped canal in 5.0 %, and one in 0.4 %. 2. In mandibular second molar, three canals was observed in 53.2 %, four in 22.2 %, two in 14.9%, C-shaped canal in 9.1 %, and one in 0.6%. 3. In the results of the percentage of 4 canals of mandibular first molars at various age, before age 20, 37.7 % was obtained whereas 19.3 % after 30. 4. 7.94 % of mandibular first molars examined were found to have three roots. 5. The mandibular second molar had C-shaped canals in 9.1 %.

The reconstruction of structurally compromised posterior teeth is a rather challenging procedure. The tendency of endodontically treated teeth (ETT) to fracture is considerably higher than vital teeth. Although posts and core build-ups followed by conventional crowns have been generally employed for the purpose of reconstruction, this procedure entails sacrificing a considerable amount of residual sound enamel and dentin. This has drawn the attention of researchers to fibre reinforcement. Fibrereinforced composite (FRC), designed to replace dentin, enables the biomimetic restoration of teeth. Besides improving the strength of the restoration, the incorporation of glass fibres into composite resins leads to favorable fracture patterns because the fibre layer acts as a stress breaker and stops crack propagation. The following case report presents a technique for reinforcing a badly broken-down ETT with biomimetic materials and FRC. The proper utilization of FRC in structurally compromised teeth can be considered to be an economical and practical measure that may obviate the use of extensive prosthetic treatment.

Introduction: This study examined the treatment patterns of temporomandibular disorders (TMD) including conservative and surgical procedures. Materials and Methods: Patients with TMD who visited Gangnam Severance Hospital from June 2007 to May 2008 were enrolled in this study. All patients were examined from the orthopantomogram, temporomandibular joint (TMJ) tomography, and a clinical examination. The patients who required a further evaluation were examined by magnetic resonance imaging and/or computed tomography. The treatment patterns were divided into counseling, medication, splint therapy, botulinum toxin injection (BTI) and surgical treatment. Results: Among the 2,464 patients, the average age was 31.8 years (ranging from 6 to 93); 764 (31.0%) were male and 1,700 (69.0%) were female. 2,355 (95.6%) patients were treated with conservative therapy; 1,460 (62.0%) patients were treated with medication, 931 (39.5%) patients were treated with splint, and 46 (2.0%) were treated with BTI. There were 109 (4.4%) patients treated surgically. Eight (0.3%) patients were treated with total temporomandibular joint replacement surgery. Conclusion: Almost all patients with TMD were treated using conservative methods. Those patients who received surgical treatment because of an ineffective response to conservative treatment had definite problems with the internal derangement and/or osteoarthritis or had severe clinical symptoms.

Duodenal perforation has a high incidence of complications and mortality if not detected and treated early. Delayed diagnosis of duodenal perforation is frequent because patients rarely complain of any symptoms. We report a case of duodenal perforation that appeared after trauma and was cured by using conservative treatment.

Among dental traumas, horizontal root fractures are relatively uncommon injuries. Proper initial management and periodical evaluation is essential for the successful treatment of a root-fractured tooth. If pulpal necrosis develops, endodontic treatment is indicated, exclusively for the coronal fragment. Fragment diastases exert a great influence on healing at the fracture line and on pulpal necrosis. An adequately treated root-fractured tooth has a good prognosis. This case report describes the treatment and 2-yr follow up of 3 maxillary central incisors, first with horizontal root fracture, second with horizontal root fracture and avulsion, and third with horizontal root fracture and lateral luxation. All three cases were treated with mineral trioxide aggregate (ProRoot, Dentsply). During 2 yr of follow-up evaluation, the root-fractured teeth of the present patients were well retained in the arch, showing periodontal healing, even after endodontic treatment.

The aim of this study was to investigate the success rate of endodontic microsurgery. Three calibrated examiners evaluated a total of 51 teeth that were treated with endodontic microsurgery in Samsung Medical Center, Seoul, Korea, during the period of 1996-2000. The periapical radiographs were evaluated and compared with the preoperative and follow-up radiographs. In addition, a standardized questionable was used to assess the clinical status of each tooth. The data was integrated and each case was categorized as being a clinical success, questionable success or a failure.(omitted)

It is generally agreed that endodontic success often depends on canal debridement, disinfection and canal obturation. Access opening to a canal is one of the key to canal debridement. Advantages of straight line access opening are allowed a greater proportion of the root canal walls to be prepared than conventional lingual access cavities, minimized the loss of the tooth structure, reduced incidence of file fracture in curved canals. The purpose of this study is determine the influence of different access opening methods on fracture strength in endodontically treated teeth.(omitted)

Purpose: Zone I fractures of the fifth metatarsal bone can generally be treated by conservative methods while both surgical and conservative methods are used for zone II fractures. However, the clinical results of conservative treatment have been rarely reported. The purpose of this study is to report the clinical results of conservative treatment for zone I and II nondisplaced fractures. Materials and Methods: Between July 2007 and August 2008, consecutive thirty seven patients (38 fractures) with zone I and II fractures of the fifth metatarsal bone were treated with tolerable weight bearing and minimum duration of immobilization based on pain on weight bearing. We evaluated the duration of immobilization, time to clinical and radiographic union, and time to pre-injury activity level. Results: Clinical and radiological union were achieved in all patients without any complications including malunion or nonunion. The mean duration of immobilization was 28.7 days. The mean 33.1 days and 48.9 days were required for clinical union and radiographic union respectively, after the initial injury. The mean time to pre-injury activity level was 4.8 months. Conclusion: Our study shows that the acute nondisplaced zone I, II fracture of fifth metatarsal bone can be treated effectively using tolerable weight bearing and minimum duration of immobilization, which is based on the pain on weight bearing.
